Detailed Description

In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

(1) In the embodiments of the present application, the terms "network" and "system" are often used interchangeably, but those skilled in the art can understand the meaning.

(2) In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

(3) "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The second device in the embodiment of the present application may be a terminal or other devices. A terminal, also referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a user, such as a handheld device with a wireless connection function, a vehicle-mounted device, etc. Currently, some examples of terminals are: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (smart security), a wireless terminal in city (smart city), a wireless terminal in home (smart home), and the like.

The first device may be a Radio Access Network (RAN) node (or device) that is a node (or device) in a radio access network or some other device. Such as a base station. Currently, some examples of RAN nodes are: a gbb, a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a Base Band Unit (BBU), or a wireless fidelity (Wifi) Access Point (AP), etc. In addition, in one network configuration, the RAN may include a Centralized Unit (CU) node and a Distributed Unit (DU) node.

The communication architecture applicable to the embodiment of the present application may be an access network architecture in a 5G system, an Evolution version of a Long Term Evolution (LTE) system, or other Orthogonal Frequency Division Multiplexing (OFDM) system or Discrete Fourier Transform Spread OFDM (DFT-S-OFDM) system, and should not be limited.

Some contents of the embodiments of the present application are described with a base station and a terminal as examples.

The network architecture described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation to the technical solution provided in the embodiment of the present application, and it is known by a person skilled in the art that as the network architecture evolves, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

When the base station configures a plurality of SRS resources (SRS resources) for the terminal, the base station can indicate SRS transmission corresponding to the SRS resource selected by the base station to the terminal through the SRI, so that the terminal is helped to determine an antenna corresponding to uplink transmission, send precoding, receive precoding corresponding to downlink transmission and the like. The precoding may be digital beamforming and/or precoding, or analog beamforming and/or precoding, or digital and analog hybrid beamforming and/or precoding.

For example, when the uplink transmission is codebook-based uplink transmission, the base station may configure a plurality of SRS resources for the terminal. And the terminal transmits the corresponding SRS according to the SRS resource configuration information transmitted by the base station. The base station sends SRI, Transmitted Precoding Matrix Indicator (TPMI) and Transmitted Rank Indicator (TRI) information to the terminal according to the received SRS. According to the SRI, the terminal may determine the SRS resource selected by the base station, so as to determine that the uplink transmission uses the same antenna and antenna port (possibly including analog beamforming) as the SRS transmission corresponding to the SRS resource. Through the TPMI and TRI information of the SRS resource corresponding to the SRI, the terminal can further determine the precoding and the number of transmission streams for uplink transmission.

For another example, when the uplink transmission is non-codebook-based uplink transmission, the base station may configure a plurality of SRS resources for the terminal and indicate, through the SRI, the SRS resource selected by the base station. And the terminal can determine that the uplink transmission uses the precoding which is the same as the precoding used by SRS sending corresponding to the SRS resource indicated by the SRI according to the SRI. If each SRS resource is configured to be 1 antenna port, the terminal may also determine the number of streams of uplink transmission according to the number of SRS resources indicated by the SRI.

For another example, when the SRS is used for antenna selection, the base station may indicate the antenna selected by the base station to the terminal through the SRI, so that the terminal performs uplink transmission using the corresponding antenna.

For another example, when the SRS is used for beam management, the base station may indicate, to the terminal, the uplink transmission beam or the reception beam selected by the base station through the SRI, so that the terminal may perform uplink transmission using the corresponding beam.

The base station may configure some SRS resources for the terminal.

The base station may also configure one or more SRS resource sets (SRS resource sets) for the terminal. One SRS resource set configuration (SRS resource set) may include one or more SRS resource configurations, and one SRS resource configuration may include an SRS resource ID, an SRS port number, an SRS time domain type indication, an SRS period, a time-frequency resource position of the SRS in one slot (slot), and the like. In general, the SRI sent by the first device indicates the SRS resource in the SRS resource set corresponding to the SRS resource received from the second device last time, and this indication method is simple but not flexible enough, which may cause the SRS received by the first device not to be needed by the first device. For example, the first device configures an SRS resource set including only periodic SRS resources for the second device, where the SRS resource set is mainly used for performing uplink channel quality measurement for low-load traffic or no data transmission. When there is a temporary high-load service, the first device triggers an aperiodic SRS resource set for the second device, and the first device expects that the second device can indicate the SRS resource in the aperiodic SRS resource set. However, if the transmission of the periodic SRS resource set is just closer to the SRI transmission time, the first device cannot indicate the SRS resource in the aperiodic SRS resource set.

On a first device side, as shown in fig. 1, the present application provides a resource indication method, including:

s101, first equipment determines SRS resources corresponding to an uplink sounding signal SRS resource indication SRI;

s102, the first device sends the SRI to the second device, so that the second device determines SRS transmission corresponding to the SRS resource indicated by the first device according to the SRI.

Optionally, in specific implementation, in the resource indication method provided in this embodiment of the present application, the first device configures at least one SRS resource set (SRS resource set) for the second device, where one SRS resource set includes at least one SRS resource.

Optionally, in specific implementation, in the resource indication method provided in this embodiment of the present application, the SRS resource set includes an SRS resource set of at least one transmission type, and the transmission type may be, for example: beamforming (BeamManagement), Codebook (Codebook), non-Codebook (noncodbook), or antenna switching (antenna switch); the SRI corresponds to an SRS resource indicated from one or more SRS resource sets of the same transmission type.

For example, when the second device is configured for codebook-based uplink transmission, the SRI in the resource indication and determination method provided by the present application only corresponds to an SRS resource indicated from an SRS resource set of a codebook-based transmission type; when the second device is configured for non-codebook based uplink transmission, the SRI in the resource indication and determination method provided by the present application corresponds to only indicating SRS resources from the SRS resource set based on the transmission type of the non-codebook. Of course, the transmission type of the transmission is not limited to the codebook and the non-codebook, and the transmission type may be specifically designed according to actual needs, and is not limited herein.

Optionally, in a specific implementation, in the resource indication method provided in this embodiment of the present application, the SRS resource corresponding to the SRI is determined according to the SRI, that is, an SRS transmission (SRS transmission) corresponding to the SRS resource is determined.

In a possible implementation method, when implemented specifically, in the resource indication method provided in this embodiment of the present application, the SRI indicates an SRS resource from an SRS resource set to which an SRS resource corresponding to an SRS received from the second device last time belongs.

Wherein the set of SRS resources comprises a set of SRS resources of at least one transmission type, the SRI corresponding to an SRS indicated from one or more sets of SRS resources of the same transmission type. The last SRS received from the second device is an SRS transmission corresponding to an SRS resource of a last certain transmission type, for example, an SRS resource based on codebook transmission or an SRS resource based on non-codebook transmission.

For example, as shown in fig. 2, t3 is the time when the first device transmits the SRI, and 1 to 4 are SRSs that the first device received from the second device 4 times before the time of t3, the first device determines that the SRS resource corresponding to the SRI is the SRS resource in the SRS resource set to which the SRS resource corresponding to the SRS 1 received from the second device last time belongs. By determining the SRS resource corresponding to the SRI as the SRS resource in the SRS resource set to which the SRS resource corresponding to the SRS received from the second device last time before the first device sends the SRI, the SRS resource corresponding to the SRI is specifically determined, so that the transmission performance of communication is improved.

In a possible implementation method, in a specific implementation, in the resource indication method provided in this embodiment of the present application, the first device determines an SRS resource corresponding to an SRI, where the SRI indicates an SRS resource from an SRS resource set to which the SRS resource corresponding to an SRS received from the second device last time in a preset time period belongs.

Further, in the resource indication method provided in this embodiment of the present application, a preset time period may be set, which may also be referred to as a preset time window, so that the SRI indicates an SRS resource set to which an SRS resource corresponding to an SRS received by the first device in the preset time period belongs. Specifically, two moments, namely a start moment t1 and an end moment t2, may be set, assuming that the moment when the first device sends the SRI to the second device is t3, t1 is not less than t3, t2 is not less than t3, t2 is not less than t1, and the preset time period is between t2 and t 1. The t2 and the t1 are non-zero integers, and the values of t1 and t2 can be configured by the first device and then are sent to the second device through signaling. When t2 is t3, and the ending time of the preset time period is equal to the time when the first device sends the SRI, that is, the preset time period is from the starting time t1 of the preset time period to the time t3 when the first device sends the SRI, the first device does not need to set t2, but only needs to set t 1. Of course, the specific setting of t1 and t2 may be determined according to actual needs, and is not limited herein. By setting the preset time period, the time period of the resource indication can be adjusted by changing the preset time period according to needs, so that the resource indication is more flexible.

Specifically, for example, as shown in fig. 3, the preset time period is [ t2, t1], t4 is a time when the first device sends the SRI, 1 to 4 are 4 times of SRSs that the first device receives from the second device before the time t4, where 2 to 4 are SRSs that the first device receives within the preset time period, and the first device determines that the SRS resource corresponding to the SRI is an SRS resource in an SRS resource set to which an SRS resource corresponding to an SRS 2 that is received from the second device last within the preset time period [ t2, t1] belongs.

By setting a preset time period, the SRS resource corresponding to the SRI is determined as the SRS resource in the SRS resource set to which the SRS resource corresponding to the SRI received from the second device last time in the preset time period belongs, and the SRS resource corresponding to the SRI is specifically determined, so that the transmission performance of communication is improved, and meanwhile, the time period of resource indication can be adjusted by changing the preset time period, so that the resource indication is more flexible.

Optionally, in a specific implementation, in the resource indication method provided in this embodiment of the present application, the SRS resource set includes SRS resources of at least one time domain type; and, different priorities are set for different time domain type SRS resources in advance.

Specifically, the time domain type of the SRS resource may be: periodic (periodic), aperiodic (aperiodic), or semi-persistent (semi-persistent). Each SRS resource set includes at least one time domain type of SRS resource, and when the first device configures an SRS resource set for the second device, the first device may configure the SRS resource set with the same time domain type of SRS resource, and when the SRS resource configured for the SRS resource set is an SRS resource of the same time domain type, the SRS resource set is an SRS resource set of the time domain type, and may also configure different time domain types of SRS resources for the SRS resource set, which is not limited herein.

Optionally, the first device may set different priorities for SRS resources of different time domain types in advance. For example, the aperiodic SRS resource has a higher priority than the semi-persistent SRS resource, and the semi-persistent SRS resource has a higher priority than the periodic SRS resource, that is, the SRS resources are prioritized as follows: aperiodic SRS resource > semi-persistent SRS resource > periodic SRS resource, or aperiodic SRS resource set > semi-persistent SRS resource set > periodic SRS resource set. For another example, the priority of the aperiodic SRS resource is greater than the priority of the semi-persistent SRS resource and the priority of the periodic SRS resource, and the priority of the semi-persistent SRS resource is equal to the priority of the periodic SRS resource, that is, the SRS resources are prioritized as follows: aperiodic SRS resource > semi-persistent SRS resource-periodic SRS resource.

In a possible implementation manner, in a specific implementation, in the resource indication method provided in this embodiment of the present application, the first device determines an SRS resource corresponding to an SRI, where the SRI indicates, from an SRS resource set to which an SRS resource corresponding to an SRS, which is received from the second device last within a preset time period and has a highest priority of a time domain type of the corresponding SRS resource, belongs.

Wherein the setting mode of the preset time interval is consistent with the above.

Specifically, for example, as shown in fig. 4, in the above-mentioned resource indication method provided in this embodiment of the present application, in a preset time period [ t1, t2], the first device receives SRSs (a 1/a2/A3/a4 in fig. 4) transmitted by the second device 7 times, where a1 is SRS transmission in which the corresponding SRS resource is a periodic SRS resource, and a2, A3, and a4 are SRS transmissions in which the corresponding SRS resource is an aperiodic SRS resource, and then the first device may determine that the SRS resource corresponding to the SRI belongs to a resource set B to which the SRS resource corresponding to the last received SRS resource with the highest priority of the time domain type of the corresponding SRS resource belongs to the SRS resource in the preset time period (i.e., a2 in fig. 4).

That is to say, if, in a preset time period, SRS resources corresponding to multiple SRSs received by the first device include semi-persistent SRS resources and periodic SRS resources, and since the priority of the semi-persistent SRS resources is higher than that of the periodic SRS resources, the first device may determine that the SRS resources corresponding to the SRI belong to an SRS resource set to which the semi-persistent SRS resources in the SRS resources corresponding to the multiple SRSs belong, which are received last time in the preset time period;

if the SRS resources corresponding to the multiple SRSs received by the first device in the preset time period include semi-persistent SRS resources and aperiodic SRS resources, and since the priority of the aperiodic SRS resources is higher than that of the semi-persistent SRS resources, the first device may determine that the SRS resources corresponding to the SRI belong to an SRS resource set to which the aperiodic SRS resources belong, which is received last time in the preset time period, in the SRS resources corresponding to the multiple SRSs;

if the SRS resources corresponding to the multiple SRSs received by the first device in the preset time period include aperiodic SRS resources and periodic SRS resources, and since the priority of the aperiodic SRS resources is higher than that of the periodic SRS resources, the first device may determine that the SRS resources corresponding to the SRI belong to an SRS resource set to which the aperiodic SRS resources belong in the multiple SRS resources received last time in the preset time period.

Optionally, if SRS resources (or SRS resource sets) of two time domain types have the same priority, and the SRS resources corresponding to the SRS received by the first device are both the SRS resources of the two time domain types, the SRI indicates that the corresponding SRS resource set is the SRS resource set to which the SRS resource corresponding to the last received SRS belongs.

Optionally, if SRS resources (or SRS resource sets) of two time domain types have the same priority, and the SRS resources corresponding to the SRS received by the first device within the preset time period are both SRS resources of the two time domain types, the SRI indicates that the corresponding SRS resource set is an SRS resource set to which the SRS resource corresponding to the SRS received last time within the preset time period belongs.

In one possible embodiment, the SRS resource set corresponding to the SRI is an SRS resource set to which an SRS resource corresponding to a last received SRS belongs, and the last time unit may be, for example, a slot. That is, if multiple SRSs are transmitted in the last slot and the SRS resources corresponding to the multiple SRSs belong to different SRS resource sets, the SRI corresponds to the SRS resource set corresponding to the SRS resource with the highest priority in the slot (if the priority is set in the SRS resource set, the SRS resource set with the highest priority here).

The priority setting may be performed by explicit priority or by pre-agreed mode. For example, the first device may pre-agree with the second device: if the aperiodic SRS resource and the periodic SRS resource exist at the same time, the SRI corresponds to the SRS resource indication of the SRS resource set to which the aperiodic SRS resource belongs, and this method also belongs to the category of the method for setting the priority in the present application. Of course, the manner of setting the priority is not limited to the above several manners, and may be specifically designed according to actual needs, and is not limited herein as long as it is feasible to conform to the principles of the present application.

Of course, the specific resource indication manner is not limited to the above manner, and may be set according to actual needs, and is not limited herein. By respectively setting priorities for the SRS resources of different time domain types, when the second device transmits the SRS by using the periodic SRS resource, if the first device needs to receive the SRS based on the non-periodic or semi-continuous SRS resource, for example, when a high-load service is suddenly required, the SRI can be ensured to accurately indicate the SRS resource selected by the first device through the setting of the priority, so that the transmission performance of communication is improved.

In a possible implementation manner, in a specific implementation, in the resource indication method provided in this embodiment of the present application, the first device determines an SRS resource corresponding to an SRI, where the SRI indicates, from an SRS resource set to which an SRS resource corresponding to an SRS, which is received from the second device last within a preset time period and has a highest priority of a time domain type of the corresponding SRS resource, belongs, the SRS resource in an SRS resource having a same priority of the time domain type of the SRS resource corresponding to the SRS.

Wherein the SRS resources include a set of SRS resources of at least one transmission type, the SRI corresponding to an SRS indicated from one or more SRS resources of the same transmission type. The last SRS received from the second device is an SRS transmission corresponding to an SRS resource of a last certain transmission type, for example, an SRS resource based on codebook transmission or an SRS resource based on non-codebook transmission.

Specifically, for example, as shown in fig. 5, in the above-mentioned resource indication method provided in this embodiment of the present application, in a preset time period [ t1, t2], the first device receives SRS (2/3/4 in fig. 5) transmitted by the second device for 3 times, other reference numerals in fig. 5 are the same as the meanings indicated in fig. 2, SRS resources corresponding to 1 and 3 in the drawing are SRS transmissions of periodic SRS resources, SRS resources corresponding to 2 and 4 in the drawing are SRS transmissions of aperiodic SRS resources, SRS resource sets to which SRS resources corresponding to 1 and 3 belong are different from SRS resource sets to which SRS resources corresponding to 2 and 4 belong, SRS resources corresponding to 2 and 4 belong are resource sets a, for example, time domain resources of different priority levels may be included in the resource sets a, then SRI is received from the second device for the last time in the preset time period, and, If an SRS resource is indicated in the SRS resource set belonging to the SRS resource of the time domain type with the highest priority corresponding to the SRS resource (2 in fig. 5) with the highest time domain type with the highest priority, then:

when the SRS resource set a includes aperiodic SRS resources and periodic SRS resources, because the priority of the aperiodic SRS resources is higher than that of the periodic SRS resources, the first device may determine that the SRS resources corresponding to the SRI are the aperiodic SRS resources in the SRS resource set a;

when the SRS resource set a includes a semi-persistent SRS resource and a periodic SRS resource, because the priority of the semi-persistent SRS resource is higher than that of the periodic SRS resource, the first device may determine that the SRS resource corresponding to the SRI is the semi-persistent SRS resource in the SRS resource set a;

when the SRS resource set a includes the semi-persistent SRS resource and the aperiodic SRS resource, the first device may determine that the SRS resource corresponding to the SRI is the aperiodic SRS resource in the SRS resource set a because the aperiodic SRS resource has a higher priority than the semi-persistent SRS resource.

Of course, the specific resource indication manner is not limited to the above manner, and may be set according to actual needs, and is not limited herein. By setting priorities for the SRS resources of different time domain types, when the second device transmits the SRS by using the periodic SRS resource, if the first device needs to receive the SRS based on the non-periodic or semi-continuous SRS resource, for example, when a high-load service needs to be performed, the SRI can be ensured to accurately indicate the SRS resource selected by the first device through the setting of the priorities, so that the transmission performance of communication is improved.

In a possible implementation manner, in the resource indication method provided in this embodiment of the present application, in a preset time period, if an SRS resource corresponding to an SRS, received by a first device and sent by a second device, belongs to multiple SRS resource sets, the first device may send, through signaling, SRS resource set indication information corresponding to an SRI to the second device.

Specifically, assuming that M SRS are received by the first device within a preset time period, where the M SRS correspond to M SRS resources respectively, and the M SRS resources belong to N SRS resource sets respectively, the first device may send SRS resource set indication information to the second device through signaling, so as to indicate which SRS resource set of the N SRS resource sets the SRI corresponds to.

Wherein the SRS resources include a set of SRS resources of at least one transmission type, the SRI corresponding to an SRS indicated from one or more SRS resources of the same transmission type. The SRS resource set indication information indicates an SRS resource set of a certain transmission type.

Specifically, in the resource indication method provided in this embodiment of the present application, for example, SRS resource set indication may be performed in all SRS resource sets configured by the first device for the second device, for example:

the bit bandwidth corresponding to the SRS resource set indication information corresponds to Log₂(N_SRS) In which N is_SRSThe SRS resource set is configured by the first device for the second device, and one state indicated by the SRS resource set represents one SRS resource set. For example, the first device configures 2 SRS resource sets for the second device, and the SRS resource set indication may be indicated by 1 bit as follows:

SRS resource set indication	Means of
		00	SRS resource set #0
01	SRS resource set #1

Specifically, one SRS resource set indication manner is to perform SRS resource set indication in all SRS resource sets corresponding to SRS transmission in a preset time period. For example:

the bit bandwidth corresponding to the SRS resource set indication information corresponds to Log₂(N_SRS) In which N is_SRSThe first device is an SRS resource set corresponding to SRS transmission for the second device, and one state indicated by the SRS resource set indicates one SRS resource set. For example, the first device configures 4 SRS resource sets for the second device, and the second device has an SRS resource set number corresponding to SRS transmission of 2, which corresponds to SRS resource set #0 and SRS resource set #1, respectively, so that the SRS resource set indication information may be indicated by 1 bit as follows:

Optionally, the SRS resource set indication Information is carried in Downlink Control Information (DCI).

Optionally, the SRS resource set indication information and the SRI indication are different regions in the DCI.

Optionally, the SRS resource set indication information and the SRI indication are jointly coded, that is, the SRS resource set indication information and the SRI indication information use the same region, for example, both indicated by the SRI, and information of the SRS resource set and the SRS resource is carried in the SRI. That is, SRI corresponds to not only SRS resource indication in one SRS resource set, but SRI corresponds to SRS resource indication from a plurality of SRS resource sets.

As an embodiment, the SRI corresponds to SRS resource indication from all SRS resources configured by the first device.

As an embodiment, the SRI corresponds to SRS resource indication in all SRS resources corresponding to SRS transmission within a preset time.

As an embodiment, the SRI corresponds to SRS resource indication in all SRS resources belonging to a certain transmission type for which there is corresponding SRS transmission within a preset time. Which transmission type the certain transmission type is may be configured by the first device through signaling.

It should be noted that the SRS resource set may include multiple transmission types, for example, the SRS resource set may include: beamforming (beamf ormanagement), Codebook (Codebook), non-Codebook (NonCodebook), or antenna switching (antenna switch); the SRS resource set indication method described above is only performed from one or more SRS resource sets of the same transmission type.

For example, when the second device is configured for codebook-based uplink transmission, the above-mentioned resource set indication information corresponds to only indicating SRS resources from the SRS resource set of the codebook-based transmission type; the above-mentioned resource set indication instruction corresponds only to indicating SRS resources from the SRS resource set of the non-codebook based transmission type when the second device is configured for non-codebook based uplink transmission.

Optionally, in a specific implementation, in the resource indication method provided in this embodiment of the present application, for example, N SRS resource set codes (SRS resource set IDs) may be respectively set for N SRS resource sets, where the SRS resource set indication information includes a code of an SRS resource set corresponding to an SRI to be indicated by signaling, and the first device sends the code of the SRS resource set corresponding to the SRI to the second device through the signaling, so that the second device determines the SRS resource set of the SRS resource indicated by the SRI.

Optionally, in the resource indication method provided in this embodiment of the present application, the signaling may be, for example, DCI, where the DCI signaling is used to schedule a Physical Uplink Shared Channel (PUSCH), and of course, the signaling may also be other signaling, which is not limited herein.

Optionally, in the resource indication method provided in this embodiment of the present application, the bit width of the signaling may be, for example, Log₂And (N), wherein N is the number of different SRS resource sets to which the SRS resource corresponding to the SRS received by the first device belongs within a preset time period.

Optionally, in the resource indication method provided in this embodiment of the present application, the second device performs, at different times, SRS transmission corresponding to the SRS resource corresponding to the SRI;

Specifically, for example, as shown in fig. 6, in the above-mentioned resource indication method provided in the embodiment of the present application, it is assumed that 5 SRS transmissions are performed in a time period from t12 to t16, and SRSs (S11/S12/S13 in fig. 6) received at times t12, t14, and t15 correspond to the same periodic SRS resource, and the SRS resource belongs to an SRS resource set C1; the SRS received at time t16 (S3 in fig. 6) corresponds to an aperiodic SRS resource, and the SRS resource belongs to SRS resource set C3; the SRS received at time t12 (S2 in fig. 6) corresponds to an aperiodic SRS resource, and the SRS resource belongs to SRS resource set C2; then, in a time period from t12 to t16, SRS resources corresponding to SRSs received by the first device belong to 3 SRS resource sets, C1, C2, and C3, respectively, the first device sends, through signaling, SRS resource set indication information corresponding to SRIs to the second device, for example, the first device sets, in the signaling, the SRS resource set indication information corresponding to SRIs to a resource set, C1, so that the SRIs perform resource indication on SRS resources in the resource set, C1;

on the other hand, the second device uses the same SRS resource in the SRS resource set corresponding to the SRI to transmit the SRS to the first device at different times, for example, at times t12, t14, and t15 in fig. 6, the second device uses the same SRS resource in the SRS resource set C1 to transmit the SRS (S11/S12/S13 in fig. 6), so that the first device may transmit, in addition to the SRS resource set indication information (SRS resource set C1) corresponding to the SRI to the second device through signaling, the transmission time information of the SRS corresponding to the SRS resource in the SRS resource set C1 corresponding to the SRI to the second device. For example, when the first device sends SRS transmission time t14 with the number S12 to the second device through signaling, the SRS resource corresponding to the SRI belongs to the SRS resource set to which the SRS resource corresponding to the SRS with the number S12 belongs.

Optionally, the transmission time instant indication of the SRS corresponds to a specific transmission time instant indication.

Alternatively, the SRS transmission timing indication may correspond to numbering of SRS transmissions corresponding to the same SRS resource or SRS resource set, and the indication of the numbering may be performed. For example, if there are 3 SRS transmissions corresponding to a certain SRS resource within a preset time, the SRS is numbered 1,2, and 3, and the corresponding number is transmitted to the second device by 2-bit coding.

Alternatively, the SRS transmission timing indication information may include only the SRS transmission number indication of the SRS resource corresponding to the SRI.

Alternatively, the SRS transmission timing indication information corresponds to the number of all SRS transmissions, and indicates the number of the corresponding SRS transmission from the SRS transmission timing indication information.

Alternatively, the SRS transmission timing indication information may be associated with the number of all SRS transmissions in the SRS resource corresponding to the RI, and indicate the number of the corresponding SRS transmission from the number of all SRS transmissions.

Optionally, the SRS resource set indication information corresponding to more SRIs and the SRS transmission time information may be jointly coded or may be separately coded, and the first device sends the SRS resource set indication information and the SRS transmission time information jointly coded to the second device through signaling, or the first device sends the SRS resource set indication information and the SRS transmission time information independently coded to the second device through signaling. Optionally, the SRS transmission timing information is jointly encoded with the SRS resource set indication and the SRI, and indicated by using the same field, for example, by using the SRI field in the DCI. Of course, the encoding method is not limited to these several encoding methods, and the specific encoding method can be designed according to actual needs, and is not limited herein.

Through signaling, the SRS resource set corresponding to the SRI and the transmission time information of the SRS are sent to the second equipment, so that the first equipment can accurately correspond the SRI to the SRS resource indicated by the first equipment, and the accuracy of resource indication is improved.

Optionally, in the resource indication method provided in this embodiment of the present application, when configuring an SRS resource set for a second device, the first device may configure the SRS resource set as an SRS resource set of a time domain type, that is, each SRS resource set corresponds to a time domain type, each SRS resource set of a time domain type only includes an SRS resource of the time domain type, for example, a periodic SRS resource set only includes a periodic SRS resource, an aperiodic SRS resource set only includes an aperiodic SRS resource, and a semi-persistent SRS resource set only includes a half-period SRS resource; the first device may transmit time domain type information of the set of SRS resources configured for the second device to the second device.

Optionally, in the resource indication method provided in this embodiment of the present application, all SRS resources in each SRS resource set correspond to the same time domain type; the SRS resource set indication information corresponding to the SRI comprises the time domain type of the SRS resource set corresponding to the SRI. The first device may send, through signaling, SRS resource set indication information corresponding to an SRI to the second device, where the SRS resource set indication information corresponding to the SRI includes a time domain type of an SRS resource set corresponding to the SRI. That is to say, the first device may set, through signaling, the SRS resource set corresponding to the SRI to the SRS resource set of one time domain type.

Preferably, the set of SRS resources of the one time domain type may be a periodic set of SRS resources. For example, the first device configures 6 SRS resource sets for the second device, where 4 SRS resource sets are aperiodic SRS resource sets, 1 SRS resource set is a periodic SRS resource set, and 1 SRS resource set is a semi-persistent SRS resource set, and then the first device sends, through signaling, SRS resource set indication information corresponding to the SRI to the second device, where the SRS resource set indication information is information of the 4 aperiodic SRS resource sets, so that the SRI only performs resource indication on SRS resources in the aperiodic SRS resource sets.

Optionally, in the resource indication method provided in this embodiment of the present application, the first device may send, in advance through a high-layer signaling, information of each SRS resource set configured for the second device to the second device. The information of the SRS resource sets may include, for example, codes (IDs) of the SRS resource sets, time domain type information of the SRS resource sets, and the like, and the first device configures the SRS resource sets for the second device, where the first device sends the information of the configured SRS resource sets to the second device through signaling, so that, in a resource indication process, the first device may perform resource indication by using the SRS resource set indication information through the signaling. Of course, the information of each SRS resource set may also be sent to the second device through other signaling, and specifically, the SRS resource set may be designed according to actual needs, which is not limited herein.

In a possible implementation manner, in the resource indication method provided in an embodiment of the present application, the method further includes:

Optionally, in specific implementation, in the resource indication method provided in this embodiment of the present application, the first device determines an SRS resource corresponding to an SRI,

and the SRI indicates the SRS resource from the SRS resource set which belongs to the SRS resource set received from the second equipment in a preset time period and which corresponds to the SRS resource set with the highest priority and belongs to the SRS resource set.

The setting mode of the preset time period is consistent with that.

Wherein the SRS resources include a set of SRS resources of at least one transmission type, the SRI corresponding to an SRS indicated from one or more SRS resources of the same transmission type. The SRS resource with the highest priority is an SRS resource of a certain transmission type, for example, an SRS resource based on codebook transmission or an SRS resource based on non-codebook transmission.

Specifically, for example, the first device configures N SRS resource sets for the second device, and the first device sets priority information to some or all of the N SRS resource sets through signaling. For example, the first device configures 6 SRS resource sets for the second device, and the first device sets priority information for 4 SRS resource sets in the 6 SRS resource sets through signaling, for example, the priority of the SRS resource set is set as: the SRS resource set 1 > the SRS resource set 2> the SRS resource set 3> the SRS resource set 4, in a preset time period, the SRS resource corresponding to the SRS received by the first device belongs to the SRS resource set 2 and the SRS resource set 4, and since the priority of the SRS resource set 2 is higher than that of the SRS resource set 4, the SRS resource corresponding to the SRI belongs to the SRS resource in the SRS resource set 4. Optionally, in a specific implementation, in the resource indication method provided in this embodiment of the present application, for example, N SRS resource sets may be respectively set with N SRS resource set IDs, and the N SRS resource sets are prioritized, that is, the N SRS resource set IDs are sorted, where the signaling includes sorting information of the SRS resource set IDs.

Optionally, in a specific implementation, in the resource indication method provided in this embodiment of the present application, an SRS resource set configured by a first device for a second device may include SRS resource sets of multiple time domain types, and the first device may also set a priority for only one or more SRS resource sets of one or more time domain types, so that an SRI only correspondingly indicates SRS resources in the SRS resource set of one or more time domain types.

Optionally, in specific implementation, in the resource indication method provided in this embodiment of the present application, the first device may also directly configure the SRS resource for the second device without configuring the SRS resource set for the second device.

Optionally, in specific implementation, in the resource indication method provided in this embodiment of the present application, the SRS resource includes at least one transmission type of resource, and the resource includes beamforming (BeamManagement), Codebook (Codebook), non-Codebook (non-Codebook), or antenna switching (antenna switch); the SRI corresponds to an indication of SRS resources from one or more SRS resources of the same transmission type.

For example, when the second device is configured for codebook-based uplink transmission, the SRI in the resource indication and determination method provided by the present application only corresponds to an SRS resource indicated from SRS resources of a codebook-based transmission type; when the second device is configured for non-codebook based uplink transmission, the SRI in the resource indication and determination method provided by the present application only corresponds to an SRS resource indicated from SRS resources of a transmission type based on a non-codebook. Of course, the transmission type of the transmission is not limited to the codebook and the non-codebook, and the transmission type may be specifically designed according to actual needs, and is not limited herein.

In a possible implementation manner, the first device configures at least one SRS resource for the second device, and the SRI correspondingly indicates an SRS resource corresponding to an SRS received from the second device last time within a preset time period.

Wherein the SRS resources include resources of at least one transmission type, and the SRI corresponds to an SRS indicated from one or more SRS resources of the same transmission type. The last SRS received from the second device is an SRS transmission corresponding to an SRS resource of a last certain transmission type, for example, an SRS resource based on codebook transmission or an SRS resource based on non-codebook transmission.

Specifically, the setting manner of the preset time period is similar to that described above, and a preset time period, which may also be referred to as a preset time window, may be set, so that the SRI indicates the SRS resource corresponding to the SRS received by the first device in the preset time period. Specifically, two moments, namely a start moment t1 and an end moment t2, may be set, assuming that the moment when the first device sends the SRI to the second device is t3, t1 is not less than t3, t2 is not less than t3, t2 is not less than t1, and the preset time period is between t2 and t 1. The t2 and the t1 are non-zero integers, and the values of t1 and t2 can be configured by the first device and then are sent to the second device through signaling. When t2 is t3, and the ending time of the preset time period is equal to the time when the first device sends the SRI, that is, the preset time period is from the starting time t1 of the preset time period to the time t3 when the first device sends the SRI, the first device does not need to set t2, but only needs to set t 1. Of course, the specific setting of t1 and t2 may be determined according to actual needs, and is not limited herein. By setting the preset time period, the time period of the resource indication can be adjusted by changing the preset time period according to needs, so that the resource indication is more flexible.

Referring to fig. 3 and the resource indication manner when the first device configures the SRS resource set for the second device, the SRS resource set only needs to be replaced with the SRS resource.

Optionally, in specific implementation, in the resource indication method provided in this embodiment of the present application, the first device configures, for the second device, at least one SRS resource including an SRS resource of at least one time domain type; for example, the time domain type of SRS resources may be: periodic (periodic), aperiodic (aperiodic), or semi-persistent (semi-persistent). When the first device configures the SRS resource for the second device, the SRS resource of one or more time domain types may be configured.

In addition, different priorities are set for SRS resources of different time domain types in advance; for example, the aperiodic SRS resource has a higher priority than the semi-persistent SRS resource, and the semi-persistent SRS resource has a higher priority than the periodic SRS resource, that is, the SRS resources are prioritized as follows: aperiodic SRS resource > semi-persistent SRS resource > periodic SRS resource.

Optionally, in the resource indication method provided in this embodiment of the present application, the priority information of the SRS resource may be sent to the second device by the first device through a signaling.

For a specific resource indication manner, as shown in fig. 4 and described above for the resource indication manner when the first device configures the SRS resource set for the second device, it is only necessary to replace the SRS resource set with the SRS resource.

Optionally, in specific implementation, in the resource indication method provided in this embodiment of the present application, the first device configures at least one SRS resource for the second device, and the SRI indicates the SRS resource from all the SRS resources that have been configured by the first device.

Optionally, in specific implementation, in the resource indication method provided in this embodiment of the present application, the first device configures at least one SRS resource for the second device, and the SRI indicates the SRS resource from the SRS resource corresponding to the SRS received from the second device within a preset time period. Optionally, in a specific implementation, in the resource indication method provided in this embodiment of the present application, for any one of the possible implementations, the precoding of the data layer for uplink transmission determined by the first device is a precoding used in the last SRS transmission corresponding to the SRS resource indicated by the SRI sent by the first device in a preset time period.

Optionally, in the Resource indication method provided in this embodiment of the present application, the signaling may be a higher layer signaling, for example, a Radio Resource Control (RRC) signaling, or may be other signaling, which may be specifically designed according to actual needs, and is not limited herein.

By setting priorities for different SRS resource sets, the SRS resource corresponding to the SRI is specifically determined in the resource indication process, and the transmission performance of communication is improved.

Optionally, in the resource indication method provided in this embodiment of the present application, after determining an SRS resource set corresponding to an SRI, the SRI indicates an SRS resource from the SRS resources included in the SRS resource set, and specifically, the indication manner of the SRS resource corresponding to the SRI may be indicated in the following manners.

For example, SRI can be employed to correspond to an indication from all configured SRS resources in the set of SRS resources. For example:

SRI indicates that the corresponding bit width corresponds to:

wherein N is_SRSIs the number of SRS resources, L, included in the configuration of the set of SRS resources_maxIs the maximum number of streams supported by PUSCH transmission. One state of the SRI represents one or more SRS resources. For example, the SRS resource set includes 4 SRS resources, and the maximum number of streams supported by PUSCH transmission is 1, the SRI may be indicated by 2 bits as follows:

SRI	means of
		00	SRS resource #0
01	SRS resource #1
		10	SRS resource #2
11	SRS resource #3

SRI indicates that the corresponding bit width corresponds to:

wherein N is_SRSThe number of SRS resources included in the SRS resource set configuration, and one state of the SRI indicates one or more SRS resources. For example, if the SRS resource set includes 2 SRS resources, the SRI may be indicated by 2 bits as follows:

SRI	means of
		00	SRS resource #0
01	SRS resource #1
		10	SRS resources #0 and #1
11	Reservation

SRI indicates that the corresponding bit width corresponds to: log₂(N_SRS) In which N is_SRSIs the number of SRS resources included in the SRS resource set configuration, and one state of the SRI indicates one SRS resource. For example, if the SRS resource set includes 2 SRS resources, the SRI may be indicated by 1 bit as follows:

optionally, after determining the SRS resource set corresponding to the SRI, the SRI indicates SRS resources from the SRS resources included in the SRS resource set correspondingly, and the SRI indicates SRS resources from the SRS resource set corresponding to SRS transmission within a preset time period. For example:

SRI indicates that the corresponding bit width corresponds to:

wherein N is_SRSThe SRS resource set has corresponding SRS resource number L sent in a preset time period_maxIs the maximum number of streams supported by PUSCH transmission. One state of the SRI represents one or more SRS resources. For example, the SRS resource set configuration includes 4 SRS resources, but only 2 SRS resources are transmitted in a predetermined time (SRS resources #1 and #3 are assumed), and the maximum number of streams supported by PUSCH transmission is 1, then the SRI may be indicated by 1 bit as follows:

SRI	means of
		00	SRS resource #1
01	SRS resource #3

SRI indicates that the corresponding bit width corresponds to:

wherein N is_SRSThe number of SRS resources corresponding to SRS transmission in a preset time period in the SRS resource set is set, and one state of the SRI indicates one or more SRS resources. For example, the SRS resource set configuration includes 2 SRS resources, and both SRS resources have corresponding SRS transmission in a preset time period, so the SRI may be indicated by 2 bits as follows:

SRI indicates that the corresponding bit width corresponds to: log₂(N_SRS) In which N is_SRSThe number of SRS resources corresponding to SRS transmission in the SRS resource set in a preset time period is indicated, and one state of the SRI indicates one SRS resource. For example, the SRS resource set configuration includes 2 SRS resources, and only 1 SRS resource has corresponding SRS transmission in a preset time period, so that SRI indication is not required.

Optionally, the SRI is carried in DCI.

Similarly, the SRI may correspond to SRS resource indication from an SRS resource of a certain priority (e.g., the highest priority, such as periodic) in the determined SRS resource set in some specific manner:

SRI may be employed to correspond to an indication from all configured priority SRS resources in the set of SRS resources. For example:

SRI indicates that the corresponding bit width corresponds to:

wherein N is_SRSIs the number of SRS resources, L, of the priority included in the configuration of the SRS resource set_maxIs the maximum number of streams supported by PUSCH transmission. One state of the SRI represents one or more SRS resources. For example, the SRS resource set includes 4 SRS resources with the priority, and the maximum number of streams supported by PUSCH transmission is 1, the SRI may be indicated by 2 bits as follows:

SRI	means of
		00	SRS resource #0 of this priority
01	SRS resource #1 of this priority
		10	SRS resource #2 of this priority
11	SRS resource #3 of this priority

SRI indicates that the corresponding bit width corresponds to:

wherein N is_SRSThe number of SRS resources of the priority included in the SRS resource set configuration, and one state of the SRI indicates one or more SRS resources. For example, if the SRS resource set includes 2 SRS resources with the priority, the SRI may be indicated by 2 bits as follows:

SRI indicates that the corresponding bit width corresponds to: log₂(NSRS) in which N_SRSThe number of SRS resources of the priority included in the SRS resource set configuration, and one state of the SRI indicates one SRS resource. For example, if the SRS resource set includes 2 SRS resources with the priority, the SRI may be indicated by 1 bit as follows:

SRI	means of
		00	SRS resource #0 of this priority
01	SRS resource #1 of this priority

SRI may be employed to indicate from all (within a preset time) of the set of SRS resources that there is a corresponding SRS transmission in the priority SRS resources. For example:

SRI indicates that the corresponding bit width corresponds to:

wherein N is_SRSIs the number of SRS resources, L, of the priority that have corresponding SRS transmissions in the configuration of the SRS resource set (within a predetermined time period)_maxIs the maximum number of streams supported by PUSCH transmission. One state of the SRI represents one or more SRS resources. For example, the SRS resource set includes 4 (within a preset time) SRS resources with the priority corresponding to the SRS transmission, and the maximum number of streams supported by PUSCH transmission is 1, the SRI may be indicated by 2 bits as follows:

SRI indicates that the corresponding bit width corresponds to:

wherein N is_SRSThe number of SRS resources with the priority of corresponding SRS transmission included in the SRS resource set configuration (within a preset time), and one state of the SRI indicates one or more SRS resources. For example, if the SRS resource set includes 2 SRS resources (within a predetermined time) with corresponding SRS transmission priority, the SRI may be indicated by 2 bits as follows:

SRI indicates that the corresponding bit width corresponds to: log₂(N_SRS) In which N is_SRSThe number of SRS resources with the priority of corresponding SRS transmission included in the SRS resource set configuration (within a preset time), and one state of the SRI indicates one SRS resource. For example, if the SRS resource set includes 2 SRS resources (within a predetermined time) with corresponding SRS transmission priority, the SRI may be indicated by 1 bit as follows:
